The Climate Projections Atlas of Friuli-Venezia Giulia (Italy)

The climate projections atlas of the Friuli-Venezia Giulia region (Italy) is a tool created to raise awareness and support decision-making in matters related to climate change. The data illustrated in this platform represent the climate projections of daily data that cover the 1971-2100 time frame for the climate models EC-EARTH-CCLM4-8-17, EC-EARTH-RACMO22E, EC-EARTH-RCA4, e MPI-ESM-LR-REMO2009 and the climate variables of average temperature (tas), maximal temperature (tasmax), minimal temperature (tasmin), and average precipitation (pr) according to the intermediate emission scenario RCP4.5 (IPCC AR5). The data miss bias-correction, which is planned and future versions of the platform will host bias-corrected data. The source of the data is the Regional Agency for the Environmental Safeguard of the Friuli-Venezia Giulia (ARPA FVG). Area Science Park has processed the data, realized and maintains the platform. The climate projections atlas illustrates the future climate in the Friuli-Venezia Giulia region according to the scenario, models, and climate variables described previously. The interactive buttons positioned on the bottom of the report pages allow to navigate the maps, graphs, and summary tables helpful in interpreting the data. The buttons temperature and precipitation show the average monthly and annual values of average temperature and precipitation whereas the buttons average temperature and average precipitation show the anomalies of average temperature and precipitation. The buttons hot days, cold days, wet days, and dry days show the anomalies of: i) frequency (number of days in a season with temperatures/precipitations above the 95th percentile for a given municipality), ii) intensity (average maximal temperature or mm of precipitation of days above 95th percentile for a given municipality), iii) length (average length of consecutive days with temperatures and/or precipitations above the 95th percentile for a given municipality). The data compares the historical (1990-2020) time frame with the short term (2020-2040), medium term (2040-2070), and long term (2070-2100) time frame. At the top of the pages are positioned the filters that allow to observe the tendencies for each municipality, model, season, or time frame. On the bottom of the pages are positioned the data summary tables and the graphs that statistically compare the tendencies of the historical time frame with those of the short term, medium term, or long term time frame according to the non-parametric statistical Mann-Kendall test. The summary of these analyses is shown at the bottom of each page and in the summary page that also contains a summary table that can be used to perform climate audits (e.g: the Covenant of Mayors climate audit). In this case, it is recommended to set the filters of the model to model average, the season to year, and the time frame to short term. In the summary page, the option model average represents the preponderant tendency of the models, whereas in the remaining pages the model average represents the average of the variable values.

The climate projections atlas can be reproduced for any region or municipality, model and variable of any spatial and temporal resolution.
